工作常用代码

1、数组判空

当定义数组时，为了防止数组越界异常，要对数据进行判空，并抛异常

if（ArrayUtil.isEmpty(xxx)）{    //为空是true，不空为false

	throw new Exception("XXXXX!")

}

2、校验只能是中文

public static boolean isChineseStr(String str){
        Pattern pattern = Pattern.compile("[\u4e00-\u9fa5]");
        char c[] = str.toCharArray();
        for(int i=0;i<c.length;i++){
            Matcher matcher = pattern.matcher(String.valueOf(c[i]));
            if(!matcher.matches()){
                return false;
            }
        }
        return true;
    }

		String str = "中文1";
        if (!isChineseStr(str)){
            System.out.println("不是");
        }else{
            System.out.println("是");
        }

3、校验是否为纯数字

		String BasicAccessNumber = "123";
        Pattern pattern = Pattern.compile("[0-9]*");
        Matcher isNum = pattern.matcher(BasicAccessNumber);
        if (!isNum.matches()) {
            System.out.println("非纯数字");
        }
        System.out.println("为纯数字");

4、校验是否有回车

		String GroupCustomerName = "哈哈"+'\n'+"哈哈";
        if (GroupCustomerName.indexOf('|') > -1 || GroupCustomerName.indexOf("\n") > -1){
            System.out.println("有回车");
        }else {
            System.out.println("没回车");
        }

5、StringUtils.contains()的用法

前边是否包含右边

		String OperationType = "新增";
        if (!StringUtils.contains("新增,更新,删除", OperationType)){
            throw new Exception("操作类型不在取值范围内：新增,更新,删除");
        }

6、时间格式转换

如果不是年月日时分秒，拼接为时分秒格式，通过长度来判断的

		String skipStartDateStr = "2021-12-03 18:41:06";
        Timestamp skipStartDate= null;
        if (skipStartDateStr.length() < 11){
            skipStartDate= Timestamp.valueOf(skipStartDateStr+" 00:00:00");
        }else {
            skipStartDate= Timestamp.valueOf(skipStartDateStr);
        }
        System.out.println(skipStartDate);

		String skipStartDateStr= "2021-09-08";
        System.out.println(skipStartDateStr.length());
        Timestamp skipStartDate= Timestamp.valueOf(skipStartDateStr+" 00:00:00");
        System.out.println(skipStartDate);

7、接口调用，5355账户资金科目查询接口

		HashMap inMap = new HashMap();
        inMap.put("busiType", "9");
        inMap.put("billId", "19502133373");
        inMap.put("targetItemId", 5960265);

        IPublicQueryServiceSV publicQueryServiceSV = (IPublicQueryServiceSV) ServiceFactory.getService(IPublicQueryServiceSV.class);
        Map map = publicQueryServiceSV.publicQueryService_5355(inMap);

8、ESOP接口调用

查询实例信息

		Map inMap = new HashMap();
        inMap.put("CUST_ID", "23010102722344");
        inMap.put("BATCH_ID", "21232792098406");
        IEsop2CrmBusiSV iEsop2CrmBusiSV = (IEsop2CrmBusiSV) ServiceFactory.getService(IEsop2CrmBusiSV.class);
        iEsop2CrmBusiSV.queryHotelInfo(inMap);

9、集团状态修改整体逻辑

		String zt = "";
        int bs = -1;
        int number = 0;
        if (zt == "失效"){
            bs = 6;
        }else {
            if (number == 0){
                if (bs != 1){
                    bs = 3;
                }
            }else if (number > 5){
                bs = 2;
            }else if (number >0 && number <= 5){
                if (zt == "沉默") {
                    bs = 5;
                }else {
                    bs = 2;
                }
            }
        }
        System.out.println(bs);

10、Csf接口调用方式

	    Map paramMap = new HashMap();
        paramMap.put("busiType","9");
        paramMap.put("billId","19502133373");//1通过 0不通过
        //paramMap.put("targetItemId","5960265");//1通过 0不通过
        paramMap.put("targetItemId",5960265);

        Map retMap = (Map) CsfServiceCaller.call("rboss_IQueryServiceCSV_publicQueryService_5355", paramMap);
        if (retMap == null || retMap.get("fee") == null) throw new Exception("查询手机号费用异常");
